Equation:
It contains variables , signs , and equal sign
for example:
x+3=y-9
Expression:
It does not contain equal sign everything else is same
now, we will verify each option
option-A:
An equation contains variables; an expression never does
expression can also contain variables
so, this is FALSE
option-B:
An equation contains an equal sign; an expression does not
So, this is TRUE
option-C:
Both expressions and equations contain numbers and/or variables
so, this is TRUE
option-D:
An expression has addition and subtraction; an equation never does
Equation can have subtraction and addition sign as well
so, this is FALSE
option-E:
An expression involves multiplication, but equations only use addition
Both can have multiplication and addition
so, this is FALSE
